OF ARKANSAS. 87 
of Newton county, has taken advantage of this natural rock-house, to 
make it serve as a roof, back, and part of the side walls to a house; closing 
in the south front with pine slabs, on either side of a stone chimney, and 
cutting two doors and windows, he has managed to construct, at little ex- 
pense and labor, a long, narrow room, about 8 by 80 feet, in which I found 
two families, numbering 8 to 10 persons residing at the time of my visit. 
Though somewhat contracted in the back part of the apartment, from the 
sloping nature of the ceiling to the north; still as the overhanging ledges 
are sound and impervious to water, this half-natural and half-artificial 
dwelling, I found more comfortable than many log cabins met with in the 
Western States. 
Plate. No. 10, is a sketch of this rock-house dwelling, taken from the 
south-east. 
The primeval forest and vegetation surmounting the entablature of the 
vestibule, reminded me forcibly of some of those remarkable habitations 
exhumed by the enterprise of Stephens, in Yucatan, which have been so 
interestingly and ably described by him, and beautifully depicted by 
the artist Catherwood. Many of these, it will be remembered, had large 
trees growing on the roof, and were often so completely concealed by dense 
jungle, that they were only disclosed by the use of the machete, axe, and 
shovel. 
CARROLL COUNT Y—Conrinvzp. 
The marble limestone is well developed in the southeast corner of Car- 
roll county, as well as in adjacent sections of land in Newton, Searcy, and 
Marion counties. On Marshall’s creek it is underlaid by a sandstone, mostly 
white, soft, and possessing the saccharoidal character of the sandstone 
observed under the cavernous limestones of Lafferty creek, in the north- 
western part of Independence County, and no doubt, occupies the same 
geological horizon as the sandstone represented in plate 4, overlying the 
lead-bearing rocks of the eastern part of this county, and the western part 
of Marion. | : 
The block of marble sent from Arkansas, to be placed in the national 
Washington monument, was quarried near the corner of Carroll and 
Newton counties. 
At a tan-yard on Davis’ creek, I saw a slab of this rock eight feet by two 
and a half, which had been got out fora currier’s table. The predomi- 
nating color of this rock is gray, mottled and clouded with liver-colored 
spots and stains. This slab was dressed smooth, but not polished; when
